In this review, we will be comparing RW-100SW and ProSub 800, two Powered Subwoofer speakers from Klipsch and Definitive Technology. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of Klipsch RW-100SW and Definitive ProSub 800 first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.
Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both Klipsch RW-100SWand Definitive ProSub 800 have a single woofer setup however the Klipsch RW-100SW's woofer is 10-inch whereas the Definitive ProSub 800 features a 8-inch woofer.
Frequency Response
RW-100SW has a frequency range of 27-125 Hz whereas ProSub 800 has a frequency range of 20-150 Hz. With a minimum frequency of 20Hz, the ProSub 800 can go significantly deeper on the low side and provide stronger bass compared to the RW-100SW's min frequency of 27Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Subwoofer class in our database.

Cabinet Type
The Klipsch RW-100SW has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the Definitive ProSub 800 have Passive Radiator type enclosure. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed designs.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Klipsch RW-100SW's and Definitive ProSub 800's external dimensions. Klipsch RW-100SW has external dimensions of 383.0 x 383.0 x 472.0mm (15-1/16inch x 15-1/16inch x 18-9/16inch) whereas Definitive ProSub 800 has external dimensions of 328.0 x 262.0 x 423.0mm (12-7/8 x 10-5/16 x 16-5/8inch).
Klipsch RW-100SW is clearly the larger of the two speakers. Its body is 121mm wider, 55mm taller and 49mm deeper than Definitive ProSub 800.
Below you can see the front view size comparison of Klipsch RW-100SW and Definitive ProSub 800 in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Klipsch RW-100SW is approximately 1807.8cm2 / 280.2inch2 and base area of the Definitive ProSub 800 is approximately 1108.3cm2 / 171.8inch2. The RW-100SW requires 63% more surface area than the ProSub 800 which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a subwoofer may become an important factor if you need to move and reposition the unit often to find the optimal positioning, also known as 'Subwoofer Crawling'. The Klipsch RW-100SW weighs 17.73kg / 39lbs and the Definitive ProSub 800 weighs 11.82kg / 26lbs. This makes the RW-100SW 50% heavier than the ProSub 800.
Here is a comparison of how RW-100SW and ProSub 800's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
Klipsch RW-100SW needs about 63% more floor area. Klipsch RW-100SW stands 49mm further into the room. Klipsch RW-100SW is 55mm taller.

A ported subwoofer against a passive radiator one. That is the most consequential line on this page: it decides how the bass rolls off, how it behaves in a small room, and how much output you get for the size of the box.
| Area | Better | Why |
|---|
| Bass depth | B | Definitive ProSub 800 goes deeper - 20Hz against 27Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | Definitive ProSub 800 has the bigger amplifier - 300W against 225W RMS, about 1.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch RW-100SW moves more air: 10" against 8" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | Klipsch RW-100SW is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; Definitive ProSub 800 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Speaker-level inputs | B | Definitive ProSub 800 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Wireless option | depends | Only Klipsch RW-100SW offers a wireless link. It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Phase control | A | Klipsch RW-100SW has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Cabinet size | depends | Definitive ProSub 800 is about 47% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Warranty | B | Definitive ProSub 800 carries 3 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | Klipsch RW-100SW costs less - $350 against $399, about 12% less. |
A Klipsch RW-100SW B Definitive ProSub 800
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Definitive ProSub 800 measures better, Klipsch RW-100SW costs about 12% less. In a normal room, placement will make a bigger difference than the gap between these two. Check your amplifier first: if it has no subwoofer or preamp output, Definitive ProSub 800 is the only one of these two you can connect at all. If placement is the constraint - a corner, behind a sofa, under a desk - Definitive ProSub 800 is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
